4. Proving Statements about Segments and Angles
Sign In
To prove that the acute angles of a right triangle are complementary, we only need information about the angles. Therefore, we can disregard the given information about the segments. Given: &∠ M is a right angle Prove: &The acute angles of a right &triangle are complementary.
To prove statements about the sides of the triangle, we can disregard the information about the angle. Therefore, we can write a given and prove statement for the conclusion in Part B. Given: &MN≅ NJ and JK≅ KL Prove: &The segment connecting the &midpoints of two sides of a &triangle is half as long as &the third side
